Free space optical communication systems suffer significant deterioration from optical turbulence during beam propagation. However, optical turbulence has yet to be reliably characterized, especially in the maritime environment. Structured light has been shown to mitigate the effects of optical turbulence. Additionally, light carrying orbital angular momentum (OAM) exhibits the property of orthogonality. This allows Laguerre-Gaussian beams to be overlaid without interference, in theory allowing for data transfer rates in the terabits per second range. Using machine learning to classify the beams, a communications system utilizing OAM can perform with >99% reliability in the maritime environment.
